Czech Republic to Modernize Control Systems at Dukovany Nuclear Power Plant
Two Czech technology companies have been contracted to modernize the control systems at the Dukovany nuclear power plant in the Czech Republic. The project involves replacing control systems for both primary and secondary circuits in all four VVER-440 reactors over a ten-year period, ensuring stable operation during the work.
The state energy company ČEZ is leading the investment. ZAT will provide the SandRA control system and has developed the technical project plan since 2020. I&C Energo will manage installation and engineering services.
The modernization aims to allow the plant to operate for at least 60 years, extending power generation until approximately 2045-2047. The Czech Republic receives about one-third of its electricity from nuclear power.
In addition to Dukovany, the Temelín nuclear power plant operates two larger reactors. The country plans significant nuclear expansion, with a contract signed in 2025 with Korea Hydro & Nuclear Power for two new APR1000 reactors at Dukovany, aiming for construction to start around 2029.
